The Apollo sitting stool was created for the Canadian Hospitals and our high level of Infection Control standards. Take a walk around the nurses station and you will find seating that is worn through, tears exposing foam and armrest that have broken off. The Apollo is more than just another office chair, it is a medical grade stool. Upholstered in the highest rated upholstery for durability and chemical resistance, the most vulnerable areas are protected with heavy duty plastic, such as the back section that is often torn on the edge of a desk. The removable arms are field replacable and adjustable for optimal ergonomics, along with the back and height.
